Visualizing translation #4 -- People Emanating Colors

In Chapter 5 of Colorless Tsukuru Tazaki, one of the characters (Midorikawa) mentions that all people emanate colors. Apparently, it looks as though their silhouettes are surrounded by halos or are backlit. However, those colors are visible to very few people. 

When reading this, one first thinks of auras and other paranormal phenomena (http://en.wikipedia.org/wiki/Aura_(paranormal)), but that does not seem to be the intention here. The internet offers many images, most of them posted on sites that tend to be somewhat, or even very, religious in orientation.
